This was a bingeable, quick read. I probably could have rated it higher if I was rating it mostly on enjoyment. But, I just couldn't look past all of it's flaws. Writing seemed to get worse as the book went on.  Characters had absolutely zero development. And not even to mention all of the plot holes in the police and legal investigations.
I also didn't find the ending believable considering all of the information we were given throughout the book for which the first-person narration was probably the biggest reason for.
